Horizontal Vacuum Purge Nitriding Furnace Model RAV-N
Real-time atmospheric automatic control enables high-quality nitriding treatment!
In the automotive and aerospace industries, there are many components that require high wear resistance. These components, used in harsh environments, can experience performance degradation due to wear, ultimately leading to failure. Additionally, in the mold industry, extending the lifespan of molds is a critical issue to maintain high productivity and quality. Deterioration of molds due to wear and corrosion can lead to decreased production efficiency and increased costs. To address this, we have developed a nitriding and soft nitriding treatment device equipped with Parker Heat Treatment Co., Ltd.'s Nitriding Potential Control Unit "NITRONAVI." By controlling the nitriding potential [KN value], it is possible to selectively manage the steel surface to achieve compound layer-free, gamma prime phase (γ' phase), and epsilon phase (ε phase). Advanced feedback control allows for real-time management and the ability to save the history of treatment conditions in data form. **Features** - Achieves low cost, short delivery times, and high reliability due to a high standardization rate. - Flexible response to unique needs with a wide range of options. - Provides recipes to achieve the best material properties. - Support for stable operations by service engineers from Hirotsu and Parker Heat Treatment.
basic information
The equipment equipped with nitriding control has made it possible to maximize the potential of nitriding treatment while contributing to solving challenges such as reducing environmental impact and securing labor, in addition to the needs for high quality and cost reduction. We also provide recipes tailored to the product characteristics required for various steel products, such as wear resistance, corrosion resistance, and fatigue resistance. 【Benefits of this treatment】 ● Improvement of mechanical properties through surface phase control - Enhanced fatigue resistance due to the absence of a compound layer - Improved fatigue and wear resistance due to the gamma prime phase (γ' phase) - Enhanced fatigue and wear resistance due to the epsilon phase (ε phase) ● Gas nitriding treatment for hard-to-nitridize materials ● Increased productivity - Reduction of nitriding time - Decrease in ammonia gas usage 【Our Strengths】 Our company has a track record of designing, manufacturing, and selling industrial furnaces in various fields for over half a century since our establishment. As a top-class industrial furnace manufacturer for steel mills in Japan, we possess high technical capabilities and extensive know-how in nitriding treatment. We provide heat treatment solutions optimized for our customers' needs. Please feel free to contact us.
